i own a small auto repair shop. as i get older, cars get smaller. new cars are lower to the ground and the engine sits further back. good for aerodynamics and efficiency, bad for old mechanics with creaky limbs and bad backs. since i now wear glasses, i can no longer do a lot of the under dash work i used to. plus, i find myself at a technological disadvantage. i need to spend $20k plus to update my diagnostic equipment. i simply don't have it. i have a buddy that is going to retire in a couple of years and he has being urging me to go into outboard repair with him. he lives in town and doesn't have room for such an endeavor, but i do have. he knows quite a bit about them and i have the storage and repair facility to do it. i am confident that i can do the mechanical repair (power heads and lower units), but i am weak in electronic diagnosis of these motors. from an equipment standpoint, it would be a piece of cake to change over. i have most tools i would ever need for outboard work. standing at a bench or outboard motor stand is certainly more attractive to me than bending over a small car to do a valve job. what are your opinions? should i? i ain't getting any younger. where would i find a source for technical info and specialty tools?
